In this study, quantitative and pattern recognition analysis for the quality evaluation of Cinnamomi Ramulus and Cinnamomi Cortex using HPLC/UV was developed. For quantitative analysis, three major bioactive compounds were determined. The separation conditions employed for HPLC/UV were optimized using an ODS $C_{18}$ column ($250{\times}4.6$ mm, 5 ${\mu}m$) with gradient conditions of acetonitrile and water as the mobile phase, at a flow rate of 1.0 mL/min and a detection wavelength of 265 nm. This method was fully validated with respect to linearity, accuracy, precision, recovery, and robustness. The HPLC/UV method was applied successfully to the quantification of three major compounds in the extract of Cinnamomi Ramulus and Cinnamomi Cortex. The HPLC analytical method for pattern recognition analysis was validated by repeated analysis of thirty eight Cinnamomi Ramulus and thirty five Cinnamomi Cortex samples. The results indicate that the established HPLC/UV method is suitable for quantitative analysis.

Objectives : In recent years, many studies have been widely researching anti-inflammation effect of various medicinal plants. $Cinnamomi$ $Cortex$ was not enough in researching of the anti-inflammation. Moreover, there is no comparative study about extraction methods. Therefore, we investigated the inhibitory effects of $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction on Nitric oxide(NO), Prostaglandin E2(PGE2) production, Cyclooxygenase(COX)-2, inducible NOS(iNOS) expression and extracellular signal regulate kinase(ERK)1/2 phosphorylation in lipopolysaccharide(LPS) induced RAW 264.7 macrophage cell. Methods : $Cinnamomi$ $Cortex$ was extracted by EtOH and Hot water. RAW 264.7 macrophage cell viability was measured by MTT assay. Effect of $Cinnamomi$ $Cortex$ pharmacopuncture on NO and PGE2 production in LPS induced macrophages was accessed by Griess assay and enzyme-linked immunospecific assay(ELISA), respectively. Inhibition effect on COX-2, iNOS expression and ERK1/2 phosphorylation was examined by Immunoblotting assay. Results : 1. Cytotoxic effect of $Cinnamomi$ $Cortex$ pharmacopuncture by Hot water extraction in RAW 264.7 macrophages was not appeared, except $3125{\mu}g/m{\ell}$. And cytotoxic effect was not appeared in EtOH extraction method. 2. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited NO production in LPS induced macrophages significantly. 3. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited PGE2 production in LPS induced macrophages significantly. 4. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited COX-2, iNOS expression in LPS induced macrophages. Especially, it has been confirmed that COX-2, iNOS expression were effectively inhibited in Hot water extraction. 5. $Cinnamomi$ $Cortex$ pharmacopuncture by EtOH and Hot water extraction inhibited ERK1/2 phosphorylation in LPS induced macrophages. Especially, it has been confirmed that ERK1/2 phosphorylation was effectively inhibited in Hot water extraction. Conclusions : According to the results, $Cinnamomi$ $Cortex$ pharmacopuncture suppresses NO, PGE2 production, COX-2, iNOS expression and ERK1/2 phosphorylation in LPS induced macrophages. It has a potential for treating various inflammatory diseases, and Hot water extraction method could be used more extensively than EtOH extraction method.

In "Sanghanlon(傷寒論)", there are several articles to explain about Oryeongsan's syndrome. Most important articles of them are No. 72 and No. 75. Oryeongsan is explained by many doctors as a prescription to control exterior and interior, because they considered that symptoms of 72 and 75 articles were caused by exterior and interior's syndrome. Accordingly, they explained that RAMULUS CINNAMOMI(桂枝) and warm water remove exterior pathogens, and PORIA(茯笭) and others remove interior fluid retention. But considering the origin of a fluid retention, RAMULUS CINNAMOMI's effects are rather activating Yang(通陽) and warming Yang(溫陽) than removing exterior pathogens. The fluid retention is cauesd by insufficiency of Yang energy, because body fluid's spreading depends on Ynag energy. RAMULUS CINNAMOMI's effects of activating Yang and warming Yang improve the fluid retention and spread body fluid to the whole body. Some doctors use CORTEX CINNAMOMI(肉桂) instead of RAMULUS CINNAMOMI, because CORTEX CINNAMOMI's effects of activating Yang and warming Yang are better than RAMULUS CINNAMOMI's. There are many opinions about what is the main symptom of Oryeongsan's syndrome, but the difficulty in urination is understood by most doctors as the main symptom of Oryeongsan's syndrome. From the viewpoint of that, they understand that Oryeongsan's main effect is the induce diuresis. But the induce diuresis does not only mean a urination. The induce diuresis must be understood as the removing fluid retention by sweat and urine through the spreading body fluid.

Tyrosinase is a key enzyme to control the biosynthesis of melanin pigments and has two enzyme activities, namely of 1-tyrosine hydroxylase and of 1-dopa oxidase. Thus, tyrosinase is regarded as a target in skin-whitening and therapeutic intervention of local hyperpigmentation diseases. We have tested tyrosinase inhibitory activity on the water extracts of 50 species oriental medicinal plant. Among them, five medicinal plants, Linderae Radix, Clematidis Radix, Cinnamomi Cortex Spissus, Fritillariae Thunbergii Bulbus and Bulbus Fritillariae Cirrhosae were investigated strong inhibition effect. Five medicinal plants were fractionated using organic solvents (methylene chloride, ethyl acetate, n-butanol, water). Cinnamomi Cortex Spissus (ethyl acetate fraction) was investigated strong inhibition effect. Tyrosinase inhibitory activity below $IC_{50}\;40{\mu}g/ml$ is confirmed in five herbal plants that are Linderae Radix, Clematidis Radix, Cinnamomi Cortex Spissus, Fritillariae Thunbergii Bulbus and Bulbus Fritillariae Cirrhosae. Tyrosinase inhibitory levels ($IC_{50}\;{\mu}g/ml$) of each plants were 15.56, 35.02, 25.14, 15.20 and 39.77. We also investigate the effect of effective plant's fraction. in dose of $100{\mu}g/ml$, Cinnamomi Cortex Spissus (P-36) EtOAc fraction significant inhibitory effect over 50%. Clematidis Radix (P-35) and Cinnamomi Cortex Spissus (P-36) MC fraction inhibit tyrosinase each 36.60% and 43.21%. inhibitory rates of Fritillariae Thunbergii Bulbus (P-40) EtOAc and $H_2O$ fraction are 31.40% and 31.51%. Bulbus Fritillariae Cirrhosae (P-45) BuOH fraction regulate tyrosinase activity to 37.71%. We examined tyrosinase inhibitory activity of natural products and these results suggest that several herbs have potential as a new whitening material.
